How to interpret and improve your email list growth metrics
Net growth rate is the only metric that matters long term. Acquisitions without retention just fills a leaky bucket
A churn rate above 2% per month signals a content, frequency, or audience alignment problem worth investigating immediately
Adding a lead magnet to your highest traffic pages is consistently the fastest lever for lifting acquisition rate
Welcome sequences that deliver immediate value in the first 7 days dramatically reduce early churn among new subscribers
Run a re-engagement campaign on inactive subscribers before removing them to recover a portion of your dormant list
Track growth rate by source such as organic, social, and paid so you can double down on what is working best
Monthly is the most useful period for tracking email growth since it smooths out weekly spikes from individual campaigns
The projection assumes a constant growth rate. Real growth compounds faster as your audience shares and refers new subscribers
Set a list size goal in the input to see exactly which month you will hit that milestone at your current trajectory
Export the CSV projection to include in a growth report or content plan for your team or clients
